A factor analysis of six commonly used instruments associated with suicide using college students.
Determined whether six commonly used inventories which are associated with suicide (Hopelessness Scale, Zung Self-Rating Depression Scale, Scale for Suicide Ideation, Reasons for Living Inventory, Suicide Probability Scale, and the Suicide Ideation Questionnaire) overlap; all six were given to 308 undergraduates. A principal components factor analysis yielded four factors with Eigenvalues greater than 1.00. These four factors were labeled Suicidal/Negative Ideas, Reasons for Living, Self-Doubt, and Suicide Desire. Each scale or subscale had a factor loading of .4 or greater on one factor. Only the Survival and Coping Beliefs subscale of the Reasons for Living Inventory and the Suicide Ideation Questionnaire loaded on two factors. Thus, each of these six instruments accounts for unique variance in suicidality. A suicide screening battery that includes all six inventories would take approximately 20 min for college students to complete, and would be valuable in identifying different aspects of suicidality.
